钢纤维混凝土在空气、污水和海水中都呈现良好的耐腐蚀性,暴露在污水和海水中5年后的试件碳化深度小于5mm,只有表层的钢纤维产生锈斑,内部钢纤维未锈蚀,不像普通钢筋混凝土中钢筋锈蚀后,锈蚀层体积膨胀而将混凝土胀裂。 Steel fiber reinforced concrete in sea water air, sewage, and shows good corrosion resistance, exposed to the sewage and seawater after five years of specimen carbonation depth is less than 5 mm, only the surface of steel fiber to produce rusty spot, internal steel fiber does not rust, does not like ordinary reinforced concrete reinforcement corrosion, rust layer volume expansion and expansion of concrete crack.   钢纤维混凝土除抗渗性能与普通混凝土相比没有明显变化外,由于钢纤维混凝土抗裂性、整体性好,因而耐冻融性、耐热性、耐磨性、抗气蚀性和抗腐蚀性均有显著提高。 Permeability performance of steel fiber concrete and ordinary concrete compared with no obvious change, due to the crack resistance of steel fiber reinforced concrete, integral sex is good, and the freeze-thaw resistance, heat resistance, abrasion resistance and cavitation resistance and corrosion resistance are improved significantly.   掺有1.5%的钢纤维混凝土经150次冻融循环,其抗压和抗弯强度下降约20%,而其他条件相同的普通混凝土却下降60%以上,经过200次冻融循环,钢纤维混凝土试件仍保持完好。掺量为1%、强度等级为CF35的钢纤维混凝土耐磨损失比普通混凝土降低30%。掺有2%钢纤维高强混凝土抗气蚀能力较其他条件相同的高强混凝土提高1.4倍。 Mixed with 1.5% of the steel fiber reinforced concrete after 150 times of freeze-thaw cycle, its compressive strength and flexural strength decline by about 20%, while other conditions the same ordinary concrete fell by more than 60% after 200 times of freeze-thaw cycle, steel fiber reinforced concrete specimen is still intact. The strength grade of steel fiber reinforced concrete with the strength grade of 1% and strength is 30% less than that of ordinary concrete. The high strength concrete with 2 % steel fiber reinforced concrete is 1.4 times higher than that of other conditions.
